Application led June 27, 1918". Serial No. 242,332'.

To all 'who/m, t may concern Be it known that I, GEORGE E. MARLATT, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented certain posed line transferred to the face .of the.

mold, fthemoldu fllled with molten metal to form a slug orlnotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through distributing mechanism to the magazine from which they started. More particularly, it relates to machines equipped with a plurality of magazines containing matrices of different font or face, any selected one of which may be brought into action at will.

In one class of such machines, (as for instance the U. S. patents, C. Muehleisen, 786,140, March 28, 1905, and H., A. Agricola, Jr. 7 89,646, of May 9, 1905,) the magazines are arranged in constant relation to the assembler entrance havinu receivingl throats leading thereto, and the .matrix releasing escapements actuated by reeds which extend through the throats or across the lower ends of the magazines, thus requiring the matrices to pass between the reeds in their travel Jtrom the magazines to the assembler entrance. This arrangement of the actuating reeds necessarily restricts the size or thickness of the matrices which can be used in the machine, as the space between the adjoining reeds is limited and cannot be increased without altering the entire keyboard mechanism or the magazine construction. These and other disadvantages have rendered the class of machines above mentioned impractical;

Attempts to overcome the above mentioned difiiculties have been more or less unsuccessful chiefly in that they involve objectionable forms and complications of matrix escapements and also the holding'of the terminalmatrix back a distance from the discharge ends of the magazine and in changing the angle or measurement of the discharge throat immediately adjoining the magazine from that which practice has shown to be most desirable. Practice has shown that the best results are obtained if the matrices rest flush with the discharge end of the magaz1ne and the usual angle of the discharge throat developed in connection with the slngle-magazlne type of linotype is maintamed. l

My present invention is intended to avoid the above objections and aims to provide a construction wherein the matrices may be discharged from any'one of Ithe magazines into the assembler entrance without having to pass between the escapement actuating reeds, and thus to allow the use of matrices of any size or'thickness which the magazines themselves are capable of-handling. To this end especially, I provide a series of actuatmg members movable across the inner or lower magazine into operative relation to the escapements'of that magazine or those of the upper or outer magazine at will, and to per- Inlt such movement of the actuating members, I form or arrange lthe parts so as to leave a space between the lower magazine and the floor of the throat, bridging said space by means of a plate or switch which 1s shifted to open or closed position automatically according to the direction of irrevement of the actuating members.

An object of my invention is to provide a machine in which not only are the matrix releasing devices retractable and selectively registerable with relation to the magazines, but also, and in the same machine, t9 provide for the selective registration of any 'or a group of magazines with the principal or primary discharge throat.

In the accompanying drawingsg-ll have shown my invention in preferred form and by way of example andas applied to a machine of the class stated, but obviously '.many changes and variations may be made Thus, it may be applied to other forms of typographical machines, such as typesetters,

typecasters, and the like, which handle type or. Adies instead of matrices. Generally speaking, I desire it to be understood that I Vdo not limit iiiyself to an specific form or ing the escapements of inner and outer mag-4 -which they were withdrawn.

azines, and means for selectively connecting the escapments of either magazine with thev key-rods, the outer magazine, in this view, being in operable relation with the key-rods;

be of any 'wellknown or approved construction. i

It is desirable that a change from one to Fig. 2 isan enlargedl right-hand eleva\. The matrix escapement mechanism of tion ofthe mechanism shown in Fig. 1, the

relative positions of the several elements being the saine as in Fig. 1;

Fig. 3 is a perspective of a portion of thev escapement actuating mechanism shown iny Fig. 1, in which certain features hereinafter described are more clearly illustrated;

Fi 4 is an elevation similar'to Fig. 2 showing the outer magazine disassociated from its escapement.v actuating mechanism;

Fig. 5 is an elevation similar to Fig. 2, showing both the inner and outer'magaznes disassociated from-their respective escapement actuating mechanisms and in a n onoperative osition in order topermit the removal ofp the inner magazine from o erative position, .and the substitution o other magazine therefor;

Fig. 6 shows the application of this invention to a form oftypographical machine in which the magazines are selectively movable with relation to the matrix delivery channels; and v Fig. 7 is a rear elevation of a portion of the matrix escapement system, applicable to Fig. 6.

The matrices are stored according to font in the superposed 4channeled magazines 1 and 124 in registration with the fixed receiving throats 115 ofthe raceway or assembler entrance, the latter and its throats being divided by the customary Vpartition plates 116 into channels through which the matrices pass to the composing stick or assembler as theyare released from the magazine. After their composition in line, the matrices are presentedl tothe casting mechanism for the production o'f the slug and thereafter carried upward and delivered to a distributing mechanism and thence tothe magazine from .The release of the matrices from the magazines 1 and 124 is controlled by the escapements 95 thereon which arearranged in series with relation to the channels in the magazines. The c escapements of both magazines are adapted to be actuated by a common series of reeds or operating devices 120, which are controlled from the keyboard (Fig. 6) in the usual way. The parts so lfar described except as hereinafter pointed out are or may 4of the magazine and beneath the upper ears of each lowermost matrix and each of the matrix channels inthe magazine is associated with an escapement set in the usual manner.`

'A secondary series of escapement members 112 which have the form lof a comb-spring is provided, and the pawl ends 113 thereof operate through the magazine rear plate at a point between the upper and lower ears of the .second matrix from the bottom of the channel and are held 4normally self-sustained in a non-obstructing relation to said matrix. Another series of springs- 114 of similar form but without the pawl ends, bear against and hold the verge pawls in extended position across the path o f the lowermost matrices, and when the pawls 98 are actuated by the selecting units leading from the keyboard, the lowermost matrix is released and drops by gravity into the channel l115 between the vertical partition 116 and thence to the assembling elements (not shown).

The action of the ver e pawls 98 causes the outer springs 1 14 to orce the pawl-ends of the escapement springs 112 inwardly in order that they may prevent the dropping of the matrix next .above the one which has been released, and insure the coperation of the two sets of pawls. The upper, clamped ends of the springs 112 and 114 are thinner than their lower ends and the bending thereof is principally confined to the curved portions 117 on the inner and 118 on the outer i the verge pawls 98, and are bent without actuating the pawl spring. In a similar manner, the springs 114 receive an overstroke of the verge'pawls 98 cause' by an overstroke of any of the units leading from the keyboard.

The springs 114 exert a constant pressure on the verge pawls 98, but are limited in their outward. movement by a clamping plate 119, which extends downwardly over the cavities in the springs 114 formed by the curved portions 118.

An auxiliary series of keyrods 111 is provided 'for actuating the escapement mechanism of the outer magazine 1, and these rods are adapted to be moved in or out of operative relation thereto by means of a handle 122, which is positioned conveniently to the operator. 123 is associated with the escapement mechanism of the inner mgazine 124, and the arrangement of the handle 122 and its con nection with the two series of keyrods is such that the movement thereof for placing one of the series of rods 111 and 123 in operative relation with its res tive magazine escapement mechanism will automatically and simultaneously move the outer set of rods from operative relation with its escapement mechanism. y

The keyrods lll'which are associated with the; outer magazine 1 are supported in a spaced relation to each other corresponding to the relative units of the outer ina azlne escapement mechanism by means o suitable perforations or notches 25 (Figs. 2 and 6) in the channel plate 125 opposite the discharge endl of the inner magazine 124, and

the rods are movable in and extend through the said perforations. A shield 126 extends across the top of the channel 115 and alines with the bottom of the matrix channels of the inner magazine when said magazine is to be used, but when the outer magazine is to be used, this shield is retracted, leaving a gap or space between it and the inner magal zine, through which gap the actuating rods .111 pass to operative sition inv relation to the outer magazine. n position, angle and size, the top surface of the shield may correspond to the established position, angle and size of the usual discharge throat at this point. This shield covers the series of notches through which the rods 111 move whenrthe rods are in inoperative position with relation to the outer magazine, and provides a smooth liioor for vthe passage'of the matrices from the inner magazine 124. The shield is carried by a pair lor more of arms 127 arranged at op termediate thereof, and t e arms are rigidl held ona longitudinally disposed rock-sha t 128 on the rear of the channel plate 125, and have furcations129 formed on their upper ends which extend through suitable openings Another series of keyrods site ends and in-` in the shield 126 for effecting the movement of the shield.

The handle 122 is mounted on a disk 132, which is pivoted on a longitudinally disposed roclt-shaft 133. The disk 132 has a radially formed slot 134 adapted to receive and permit the movement therein of a pin 135 carried by a tubular arm 136, which telesco and slidably receives a rod 137. A spring 138 is carried by the rod 137, and is adapted to compress between the end of .the arm 136 and a pin 139 secured in the rod for the purpose of holding the rod extended from the arm to the extreme of its movement. l

. The initial downward movement of the handle 122 for raising the keyrods into operative position 'releases the arms 127, and permits their movement by means of the springs 130, which are attached at one end to the urcations 129 of the arms and at the outer end of the channel plate 125 by means of the screw 131, thus effecting the movement of the shield 126 forwardly, so that the vkeyrods 111'may pass thereby vin their upward movement.

The final movement of the handle 122.

upwardly for the the keyrods 111 moves the shield backwar y So as to cover the series of perforations in the channel plate 125, through which-the rods pass. .A pin 140 in the upper end of the rod 137 enurpose of withdrawing gages and forces the arm backwardly againstthe tension of the spring 130; the pin moves in the slot 141 in the channel plate 125 and guides the upper end of the rod 137, and when the shield 126 is thus moved, the pin 140 rests against 'the end of the slot 141. Further upward' movement for purposes which will be presently described, causes an overstroke of the tubular arm 136 against the tension of the spring 138, which is provided for the purpose of receiving the. im-

pact of the stroke in such an event.

The shield 126 has grooves 26 -in its upper surface to receive the under edge of the partitions 116, and thus maintain the partitmns in accurate alinement with relation to the channels in the magazine. Either or both 4of the edges of the shield may also have grooves or notches 27 for a similar vpurpose as indicated in the several figures of drawings and more clearlybrought out in Fig. 6.

rom o rative position die The rods 111 are substantially parallel and.' 120 in its lowermost position, and the keyrods 111 are in operative position.` A spring 148,

secured at one end to the inner end 146 of the of the frame 144 when the handle is raised towithdraw the rods 111 from operative position.

The lower ends 149 of the rods 111 are flattenedvand rounded and are pivotally held in the open bearings 150 in the upper ends of the vertical extensions 1 51 on the bars 152. The bars 152 are mounted at their inner or forward ends'on the shaft 133, as shown in Fig. 3, and the rear ends ofthe bars engage and seat in 4notches 154 1n the lower serles of keyrods 12()vv which are associated with .both magazines. i

When'. the handle 122 is raised, the bars 152 are moved downwardly by means of a horizontal extension 155 on the bottom of the frame 144, which engages notches 156 in the lower portions of the extensions 151 on the bars 152. The downward ymovement of the series of bars is limited by means of a longitudinal rod 157, which is'secured at opposite ends in the brackets 158, and extends beneath the entire series of bars.

The brackets 158 are secured to suitable portions of the machine frame at their forward ends vby means of -screws 159, the rear ends are provided with {iat-topped lugs 160, and the forward ends have upward extensions 161 in which the ends of the shaft 133 are journaled. A radially formed rib 162 extends outwardly from the bracket extension 161 and is provided with a plurality of perforations 163, 164 and 165, which are adapted to receive the tapered end 166 of the handle stem 167 for holding the handle in various selected positions relative to its axis when itis raised or lowered for the purposes set forth.

A iange 168 is formed on. the inner end of the handle stem 167 and a spring 169 is carried by the stem between the flange and the end of the guiding sleeve 170 formed on the disk 132, the spring serving to retain the inner end 166 of the stem 167 in theperforations 163, 164 and 165, as may be selected.

The handle 122 is slidably mounted on the disk 132 and it is necessary in order to change the position of the handle, to move it out- 1 Wardly from the disk 132 against the tension of the spring 169, such a movement withdrawing the tapered end of the stem from the perforations in the rib 162preparatory to placin the samein position for entrance as shown in Fig. 4. A reverse movement A'offitalie-.handle reverses the relative position .ofthe llieyrods, and further movement of the into anot er of the perforations.

The disk 132 has an inwardly extending arm 171 whichcarries one end of a longitudinally disposed shaft 172 and the other end of the shaft is carried by another similar arm at the opposite sideof the magazine. vAn arm 173is secured to each end ofthe shaft with both ends extending `from the shaft, and is pivotally connected at opposite ends with a link 17 4.by means of a screw 175',

anda shorter link 176 by means of a A`screw 177, respectively. The link 174 is pivoted at its forward end on a screw 178 to the handle 122 and ,the link 176 is pivoted at its inner end on a screw 180 to the forward end of an arm 179. The pivot screw 180 extends through an elongated slot 181 in the inner end of the disk arm 171 and the inner or rear end of the arm 179 is pivotally held .pn a longitudinally' disposed shaft -182 at the rear of the series of vkeyrods 120, the ends of the shaft being supported on the flattolgped lugs 160 on the ends of the brackets 1 l The rear upper series of keyrods 123 which are 'associated with the inner magazine 124 are slidably supported and guided near their upper and lower extremities in a frame 183, which is supportedat two or more points on the shaft 182 by means of arms 184 suitably secured to the rear wall of theframe. Each of the rods 123 has a notch 185 formed in its forward edge which receives the edge of a flat bar 186 suitably held on the lower por- -tion 187 of the frame 183, which limits the downward position of the rods and retains them in the proper alinement in the frame.

The arms 179 and 184 are resiliently eonnected by means of a spring 188, which is secured at opposite ends to the pins 189 and 190 in the arms, and lugs 191 and 192 on the arm 184 and the hub 193 of the aim179 are normally held in contact by the spring, this arrangement permitting the tilting of the frame 183 backwardly in'order to afford access to the mechanism in front of the frame. When the handle 122 is drawn forward to release the stem 167 from one ofthe perforations in the rib 162 for the purpose of lowering the series of keyrods 111, the centrally p1voted arm 173, the links 174 and 17 6, and the arm 17 9 operate to force the longitudinal frame member 194 backwardly and 4to thus' disconnect the keyrods 120 from the handle luntil the end of the stem'167 registers with the perforation 165 causes an extreme so i.

forward deflection of the keyrods 123" until their upper ends rest against the-outer magazine keyrods 111 in front of the end of the magazine 124. The object of thus placing the keyrods is for the purpose, in a certaintype of 'machina .of permitting the lowerlng and removal of the magazine 124 and the substitution therefor of another in op-- erative position. The restoration' of the keyrods tol operative position is accommeans of a reverse movement of ceive and through which the lieyrods extend. The upper side of the-frame is curved oyer in the direction of the keyrods 123, and is provided with slots 196 which register with the lower slots and which are adapted to slidably receive the upper keyrods 123.

'llhe `upper and lower series of keyrods 123 and 120 are provided, respectively, with convex and concave ends between the upper and lower slots inthe frame 194 for more effectively centering the rods one on the other.

Invthe event `that the magazine 1 is designed to accommodate matrices of extreme thicmless, it may be Wider at the discharging end than the magazine 124 and the escapement mechanisms of both magazines being actuated by the common series of keyrods 120, it is necessary to olf-set the keyrods 111 to an extent, which increases with each connecting bar 152, as the right hand edge of the magazine is approached. This is accomplished by off-setting the extension 151 of the bar-152 in one direction, and the inner or rear ends of the bars 152 in an opposite direction, as shown in Fig. 3. This view also shows very clearly the pivotal connection between the lower ends of the keyrods 111 and the extensions 151 of the bars 152.k

In Fig. 6 is shown an adaptation of this invention to the magazine arrangement and escaiement. system disclosed in the recent U. ..Patent, No. 1,266,970, (Marlatt) and to similar arrangements; In said patent, the magazines are disposed one above the other in radial lines and are movable in unison to bring any two successive magazines in distinctly new in so far as it provides. not; only for selectively registerin any two'of, a group of magazines with the eliver channels, but also for selectively connecting` the" escapement operating members with the lng, one against the other, the flattened over- 13ol registrationA with two respective delivery channels, so that matrices may be withdrawn from either of the two magazines and mixed'v in the same yline without moving the magazines.

With the exception of an optional arrange-` ment in said Patent No. 1,266,970, the arrangement of parts and combination of, features disclosed in Fig. 6 is believed to be 'amble of 'this specification.

.renders possible the mixing inl a single' line the magazine.

selected magazines-without lacing limit on thesize of the matrices y obstructing theirpassage from either operative magazine, as would be the case with theA objectionablearrangements mentioned inthe pre- Thisxieature matrices from twol magazines by utilizing both the primary and auxiliary delivery channels, but doesv not interfere with registering any one of the group of magazines with the primary delivery channel for rapid continuous assembling of the matrices. In this connection it should be understood that the magazines themselves are transposable in position, and interchangeable one with another, preferably by removing and inserting them edgewise in the manner disclosed in the above-mentioned Patent No. 1,266,970.

Certain matrix-distributing features disclosed in said patent, and which need not be here pointed out, also render the substance of said: patent particularly adaptable in connection with this present invention.

. IThe form of matrix escapement shown in Fig. 6, is particularly well adapted, in connection with the operati and lshifting mechanism heretofore described, for use inl connection with magazines disposed one above the other in parallel or approximately parallel lines.

It is desirable, in orderthat the escapey ments may be readily connected and disconnected with and from the actuating rods l 111 that the forward end of the verges should aline with the ends of the magazine.

With this and other objects in view, I

provide a series ofv duplex verges, each verge of the pair being separately pivoted .to rods 2 and 3. The two verge members are adapted to act in unison for releasing the Inatrices from 'the magazine in the 'usual manner and the co-acting verges of each escapement are resiliently connected by means of a spring 4, which restores the vergestonormal position after a matrix'hasl'been released. The springs are coiled about the wire` from which they are formed, the straight portion of, the wire extending through slots 5, (Fig. 7) in the rear end of the lforward verge and terminating in a loop around the forward llend of the rear verge. The inner ends of both. verge members have pawls 6, which extend through slots in the bottom plates of the magazine and oscillate to release the matrices'one at a time from y The operation of the forward verge 7 to release a matrix from the stores'th'eiverges to normal position byalinrear pawl, as frequently happens, then the front verge operates independently against the tension ofthe spring, permitting the forward matrix to be released. (See 2nd.

. magazine from bottom, Fig. 6).

For the purpose of this description the upper delivery channel 8 may be considered either fixed or movable. Arranged beneath it in series are pawls 9, held against the escapement levers 7 by the keyrods 111 when the keyrods are in their raised position. When the keyrods are lowered in manner similar to that heretofore described, the pawls 9 drop by turning on their pivot bar 10 to a position which permits the magazines to be/moved past them, but not so far that the ends of the keyrods will not engage and raise them when required for use. Their downward travel may for this purpose be limited by a rib 11 on the rear wall of the upper channel 8. When the keyrods are lowered to operate the escapements of the lower magazine, their upperends are moved back beneath the ends ofthe escapement'levers by means of a guide plate 12 having perforations 2O close to its rear edge through which the keyrods pass. The guide plate is attached to the shield 126 by pins 13 passing through the channel plate 125 at intervals. These connecting pins may operate in the same notches through which certain of the keyrods pass. When the shield 126 is retracted or restored in the manner hereinbefore described, the guide plate 12 is moved therewith for registering the rods with the upper or lower escapements as described. rllhe connecting levers 152 function in manner heretofore described, but the manner of connecting them with and disconnectin them from the keyrods 120 is somewhat di l ferent. A guide plate 14 i's mounted on the brackets 158 by Vmeans of a fulcrum rod 15. A link member 16 connects an extension 17 of the guide plate with the operating handle 122,- la pivot screw 20 joining a stem 19 of the handle to the connecting link 16 at a point close to the center on which the handle turns. When the handle is drawn forward to free it for moving the connecting levers 152, the guide `plate 14' guides the keyrods 120 from beneath one or the other of contact knobs 18 on the levers 152. This permits the levers 152 to be moved and when so moved the restoration of the handle 122 automatically places the keyrods 120 in engagement with the selected knob on the connecting lever 152. The final upwardl movement of the handle moves the shield 126 to close the passageway for the rods 1.11, and moves the guide platel 12 ,to engage the rods with the escapements of the lower magazine, as shown in dotted lines.

If it is desired to move thev magazines, this is done before the rods are so connected, or when the ends of the rods are at any point between the upper and lower escapements.

The descriptionof the operation of this invention havin been carried along in the body of the specifications, it is believed that the operation will now be understood.

As previously stated, I have shown my invention only in preferred form and by way of example, and it will be obvious that many modifications and alterations therein 'and in its mode of application will suggest themselves to those skilled in the art without departure from: its scope.
